Power over Ethernet (PoE) was developed to enable power (48 V DC) to be delivered to an IP device via its data cable where a separate power supply may not be available. PoE simplifies and reduces installation costs as only one cable needs to be installed, supplying both data and power. However, remembering the details of the IEEE Standard PoE Pin/Data Assignment can be difficult.
This 1-page reference flyer that you can print at your own office will serve as a quick guide for powered devices including the IEEE 802.3bt specification also referred to as PoE++ or 4PPoE (4 pair PoE).
